Video transcript

Hello everyone. And in today's video we have the following problem. The right parietal lobe of the brain is involved in were given certain functions that it could be undergoing. However, we have to pick one of the answer choices as the only correct one. So let's quickly go over the possible functions of the by parietal lobe that we are given beginning by answer choice B temperature and water balance. This is nothing more than home use stasis and this is actually going to be performed by the hypothalamus which is not going to be part of the right period of globe so we can cancel these answer choices being incorrect. Then we have speech and language. This is going to be actually performed by the frontal lobe, specifically the right hemisphere of the frontal lobe. So we are going to cancel this out as well as being incorrect. This all lives with answer choice A which is judgment in size and distance of objects and I want you to just focus on this part of judgment. What this means is that it is involved in perception and this part of insight and distance. This is site or just sensory information, vision. So what the right period of love those is basically just taking this visual information and judge it or just process it for the brain and that is precisely the function of the period a lobe. And it makes answer choice a the correct answer for this question. So thank you very much for sticking around until the end of this video. I really hope it helped you

DRAW IT The reflex that pulls your hand away when you prick your finger on a sharp object relies on a neuronal circuit with two synapses in the spinal cord. (a) Using a circle to represent a cross section of the spinal cord, draw the circuit. Label the types of neurons, the direction of information flow in each, and the locations of synapses.
